摘要： The present invention provides a rotation controller adjusting the speed of a rotary member (103). Phase difference compensating means (118) outputs a phase difference compensating signal (119) corresponding to a phase difference between a rotation signal of the rotary member (103) and a target signal, and frequency difference compensating means (114) outputs a frequency difference compensating signal (115) corresponding to a frequency difference between these signals. The rotary member (103) is braking-controlled by means of these signals. Use of the phase difference compensating signal (119) permits achievement of PLL control, and maintenance within the locking range allows a stable rotation control with a high response. Further, use of the frequency difference compensating signal (115) makes it possible to quickly bring the control within the locking range even when the rotary member (103) deviates from the target signal, and thus to carry out a control with a high response even upon riseup of the rotary member (103).

摘要： In an information device, a fingerprint image capture section captures a fingerprint image of an operator. When a fingerprint image captured by the fingerprint image capture section is referred to as a first fingerprint image and a fingerprint image captured at a given time interval after the first fingerprint image is captured is referred to as a second fingerprint image, a comparison section compares minutiae points of the first and second fingerprint images extracted by a minutiae point extraction section. An image generation section generates image information which is changed while reflecting the comparison results of the comparison section. A display section displays an image based on the image information generated by the image generation section. The information device may be provided with a check section, and display control by the display section may be performed after a fingerprint image is checked by the check section.
